I would have added the speed as a potential negative however the hand outs negate, you could easily catch up if you did fall behind. In addition, the notes provide reference to the steps exactly so you can repeat the steps and experiment/research topics further. Excellent introduction.

A great eye opener into the potential of docker. Provides a solid starting place for complete newbies like me. Some paper notes to supplement the tutorial would be very useful could even add more theory and useful links into the notes.

I agree with the comments made by Endijs Lisovskis
"This talk can easy be used as example on what we need more at PHP conferences. Entertaining start, bad code/good code examples, what to use and what not to use, passion about the subject from the speaker. Thank you! Very well done!"
